Abstract:
The case of a patient with narrow QRS-complex supraventricular tachycardia and atrial flutter is described. The 12-lead surface electrocardiogram (ECG) revealed sinus rhythm with ventricular pre-excitation and negative δ waves in leads II, III and aVF, indicating Wolff-Parkinson-White syndrome with a posteroseptal accessory pathway (AP). Coronary sinus angiography revealed the presence of a diverticulum near the coronary sinus ostium. The AP was successfully ablated using radiofrequency energy applied in the neck of the diverticulum, following several failed attempts at catheter ablation from the endocardial surface of the posteroseptal space.

Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism, and...
